Downloading PupRummyLite 2.3.5 for Mac from the developer's website was possible when we last checked. We cannot confirm if there is a free download of this app available. The actual developer of this free Mac application is YPR Software B.V. The software lies within Games, more precisely Board.
From the developer:
Pup Rummy Lite is a free Tile Rummy game for Macintosh computers. You can choose your playing level: easy, medium or hard, or let it automatically adapt to your playing strength. Also, there are three different computer players with individual playing strategies. You play your tiles in matching groups of three or more. You can use jokers as wildcard tiles.
Re-arrange tiles already on the table to create new possibilities.
You may want to check out more software for Mac, such as Monster Ball Demo, MyNevermind or Shisen-Sho, which might be similar to PupRummyLite.
